THOMAS P. MARCOTTE, OF 'WEST POLAND, MAINE.

HlsESHE-CALK.

Application filed J une 20, 1914.

To all whom t may concern:

Be it known that I, THonAs P. MAnoo'r'rn, a citizen of the United States, residing at West Poland, in the county of Androscoggin and State of Maine, have invented certain new and useful Improvement-s in Horseshoe-Calks, of which the following is a specification.

My invention relates to new and useful improvements in horseshoes and more particularly to removable calks that are provided with beveled edges to insure their gripping and are secured in ay novel manner so that breakage or derangement thereofn is obviated.

Another object is to provide novel means for fastening the toe calli that serves as a toe plate as well as fastening means and is of a novel construction.

Another object is to provide detachable calks that are of simple construction, capable of being readily attached and detached, securely held against breakage and derangement and inexpensive to manufacture.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out as claimed.

'Vith reference to the drawings. wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a perspective view of my device assembled, Fig. 2 is a detail sectional view of the toe calli assembled, Fig. 3 is a fragmentary perspective view of the shoe with toe removed, Fig. 4 is a detail perspective view of the toe calli, F ig. 5 is a detail perspective view of the combined fastener and toe plate.

Referring to the drawings by characters of reference the numeral 1 designates as an entirety the body of a horse-shoe that is formed at each end with depending lugs.

A depending or right angularly extending projection o-r fiange 12 is formed integral with the heel portion of the shoe 1 and extends transversely of said heel portion. The projection or flange 12 is provided with an enlarged portion 13 upon its rear face and centrally of its ends and through the flange or projection 12 is formed an opening 14.

Specification of Letters Patent.

Patented Mar. 1st, 1915.

Serial No. 846,322.

The projection or flange is spaced from the extreme outer edge of the toe portion of the shoe and in the outer edge portion on one face thereof is formed a semi-circular concavity or recess 15 which is arranged centrally of the ends of the proj ect-ion or flange 12. An offset and rounded portion 16 formed on a rectangular calk 17 is positioned within the semi-circular concavity 15 and lits snugly therewithin. The rectangular toe calli 17 is beveled edged and provided centrally of its ends with an opening 18 that is designed to aline with the opening 14: so that the fastening means to be later described may be inserted therethrough.

As a means for securing the toe callr 17 upon the shoe and also providing a toe plate, I provide an approximately semi-oval toe plate 19 that is offset adjacent to its larger end on one face to provide a shoulder 2O and has formed integral with said offset portion and extending outwardly at right angles thereto a cylindrical and screw threaded extension 21. threaded extension 21 is inserted through the alined openings 18 and 14 on the calk 17 and flange 12 respectively, after the calli has been positioned as described upon the shoe and in such manner that the toe plate 19 is extended upwardly from the shoe. The inner face of the toe plate is flat and abuts the flattened face 22 formed on the outer edge of the toe portion of the shoe and is thus securely held in position. rlhe enlarged central. portion 13 of the flange 12 flattened and designed to abut the inner face of a. nut 23 that is turned on the screw threaded extension 2l to extend for a considerable distance beyond said flattened face of the portion 13. It will be readily seen that the toe plate 19 and extension 21 serve to securely hold the toe calli 17 in operative position upon the shoe and in such manner that it may be readily and easily removed.

In practice, l have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, 1 desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may The cylindrical and screw be resorted to, when required, without sacri- Y a screw threaded extension formed at right angles thereto and adapted to be inserted through said calk and means itted on the screw threaded end of the extension for se curing the saine to the shoe.

In testimony whereof I aix my signature in presence of two witnesses.
